10. Repeat test 8A or 8B to check operation of the motor without the process or load. Note
for proper motor current, voltage and direction of shaft rotation. If an encoder card is
installed, set encoder parameters in the expander board menu and monitor frequency
and speed from the encoder board. Frequency should match output frequency of the
drive with a positive value for forward direction. If encoder frequency is opposite;
change motor phase order, encoder connection or select “invert” on the expander
board menu. For many pump or fan applications, no tuning is required. If further tuning
is necessary, perform the tuning while the motor is disconnected from the process.
11. Perform ID Run. Setting the identification parameter to the appropriate value Par/group
P1.6.16 followed by a start command within 20 seconds activates automatic
identification. (See test 8A or 8B for start command.) Upon completion, cancellation by
a stop command or if timely start is not received, the parameter will reset to its default
setting. Possible ID run selections are as follows:
●
OL V/f Ratio — The drive is run at zero speed to identify the motor parameters.
(Earlier system software version.)
●
OL V/f +Boost — The drive is run at zero speed to identify the motor parameters and
automatic torque boost is turned on. (Earlier system software version.)
●
Identification without motor run — The drive is run at zero speed to identify the
motor parameters.
●
Identification with motor run — The drive is run at 2/3 rated speed to identify the
motor parameters. (No load on motor.)
●
Encoder ID run — Identifies the shaft zero position when using PM motor with
absolute encoder or resolver feedback.
12. When ID Run is complete as shown by a stop indication on the keypad, reset the drive
with a stop command according to Test 8A or 8B. Set the motor control mode to
OL Speed Control, CL Speed Control if appropriate for the application and repeat
Test 8A or 8B.
13. If necessary, skip to the next section to perform manual tuning functions before
connecting the motor to the process.
14. Disconnect all power to the SVX9000/SPX9000. Wait until the cooling fan on the unit
stops and the indicators on the panel are not lit. If no keypad is present, check the
indicators in the control panel cover. Wait at least five more minutes for the DC bus to
discharge. Connect the motor to the driven load making sure mechanical system
requirements are met. Make sure that the driven load can be run safely and that no
hazard exists to any personnel. Repeat test 8A or 8B.
